DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to power connectors, and more particularly to power connectors for connecting electrical cables having a plurality of conducting wires that are connected to, for example, a printed circuit board.

[Prior art #g] A power connector is generally known and is used by connecting a contact pin protruding from a printed circuit board to an electric wire, which is a conductive wire of a cable. Large currents, in excess of 15-20 amps, are often required for printed circuit boards. The power connector has a structurally sound shape,
Must meet sufficiently stringent insulation requirements. This configuration requires precision in positioning the plug portion of the connector having the wire end of the cable to be engaged with the engaging portion of the connector that covers the contact pins of the printed circuit board.

[Object of the Invention] An object of the present invention is to provide a power connector that satisfies the above-mentioned requirements.

[Conjunction and Effects of the Invention 1 The power connector of the present invention is a rectangular connector block having a bottom, two rotatable vertical side walls, a block-shaped cover serving as a connector cover, a pin holder, and a base plate. wherein at least two parallel rows of contact pins of the contact section are vertically fixed in a chamber formed by longitudinal separation, and an end of the core of the wire of the cable is attached to the upper end of the contact section. installed. Each longitudinal sidewall has an upper portion. This upper part is pivoted outwardly around the longitudinal grooves and is curved inwardly and is provided with comb-like edges with elongated grooves, so that in the end position of their rotation the longitudinal grooves are comb-like. An elongated groove formed by a shaped edge holds the wire end and the contact portion. The block-shaped cover accommodates the connector block and the outwardly extending cable. The pin holder has at least two rows of contact pins corresponding to the contact portions and is connected to the printed circuit board. The base plate includes an elongated groove with an upright wall in which the pin holder is firmly fixed. The block-like cover and connector block engaged therein are securely fixed to the pin holder and the upright wall of the base plate, so that the contact pins are engaged in the contact parts.

[Embodiment 1] A connector block 1 of a power connector according to an embodiment of the present invention is shown in FIG. This connector block 1 has a rectangular shape and has a base 2 and a plurality of longitudinal walls 3. Each longitudinal wall 3 is turned outwardly around the longitudinal groove 13 shown in FIG. 4, resulting in the condition shown in FIG. Each longitudinal wall 3 is provided with a bent comb-like edge 4, which edge 4 has an elongated groove at its longitudinal end. This elongated groove is engaged with the conductor 11i16 of the cable 5 in the closed position of the end of the longitudinal wall 3. A contact portion 7 is joined to the exposed end of the electric wire 6. This contact part 7 is mounted upright in the chamber of the segmented connector block 1. If necessary, the connector block 3 is provided with a cable support 8 at one end. at the same time,
Cutouts 9 at both ends are provided at the flat ends of the connector block 1.

A block-shaped cover 15, which is a connector cover shown in FIG. 2, accommodates the connector block 1. As shown in FIG.

The part of the connector block 1 on the right shown in FIG. As the wires and contacts 7 are pressed onto them, they are placed in position and spaced apart.

The two longitudinal walls 3 have projections 10 projecting outwardly at right angles, which are engaged in two corresponding grooves 14 provided in the longitudinal inner surface of the block-shaped cover 15.

On the cable outlet side of the cover 15, the block-like cover 15 has another cable support part 12, with which the cable 5 is securely attached.

In the upper part of FIG. 3, a block-shaped cover 15 is shown housing the connector block 1, from which the cable 5 extends. At the bottom of this figure, the pin holder 20 of the power connector is shown. This pin holder 20 is provided on a base plate 21. The bottom of the pin holder 20 is provided with at least two rows 22 of contact pins. This row of contact pins 22 extends vertically through the bottom and is engaged with the contact portion 7. When the block-shaped cover 15 holding the connector block 1 is fitted into the pin holder 20, the contact pin array 22 is connected to the corresponding contact portion 7 of the connector block 1.
In this state, cable 5 and 6 are connected! ! The ends of ii6 are electrically connected.

Further, the pin holder 20 has a plurality of surrounding walls projecting from the bottom. For example, triangular marker pins 23 are provided near both ends of the pin holder 20.
is rotatably mounted on a polygonal, for example pentagonal, base 24. These marker pins 23 are fixed in one of five defined positions overlying the triangular cutout 9 at each end of the connector block 1. This connector block 1 is configured to receive and stop a marker pin 23. Two indicator pins 23 are provided on the pin holder 20, so that when the cover 15 is correctly installed, they will be engaged in the cutouts 9 of the corresponding connector block 1, which will allow 5X5=25 different identifications. It is possible.

At the bottom of FIG. 3 there is shown a spring 25 fixed around the upright wall of the pin holder 20, firmly fixed to the base plate 21 and having a pre-biasing force. This spring 25 is made from one piece of material and is formed as a small monolith. The spring 25 has a very important function; if the block-shaped cover 15 with which the connector block 1 is connected is not accurately positioned and fixed on the pin holder 20, the block-shaped cover 15 will be pushed out by the force of the spring. We guarantee that you will

In the longitudinal direction of this power connector, the spring 25 has two upwardly projecting spring parts 26.

The block-shaped cover 15 has a longitudinal edge 16 on each longitudinal side, so that when the cover 15 is pushed in, the cover 15
until the protrusion 27 at each end of is inserted into the opening 29.
The longitudinal edge 16 receives a repulsive force from the blade part 26.

The opening 29 is formed in the upwardly projecting spring part 28 at the end of the spring 25.

FIG. 4 is a sectional view of the power connector. The longitudinal walls 3 of the connector block 1 each have a longitudinal direction w 413 on their periphery, around which longitudinal groove 13 the longitudinal walls 3 are pivotable outwardly. When the rotating part is returned to its final closed position,
The two comb-like edges 4 of the longitudinal wall 3 are brought together, and the terminal 18 of the cable 5 is positioned in engagement with the elongated groove formed between them, and the connected contact portion 7 is positioned.

A vertical projection 10 projecting at right angles is engaged in a recess 14 on the inside of the cover 15. Further, when the cover 15 housing the connector block 1 applies pressure to the pin holder 20, the protrusion 10 is pressed against the vertical wall of the base plate 21 via the O-shaped ring 17.

Furthermore, the pin holder 20 is engaged in an elongated hole 33 in the base plate 21 which is externally moisture-proof and strongly bonded. The base plate 21 is a printed circuit board 30
It subsequently forms part of an electronic box to which it is attached. The contact pin rows 22 of the pin holder 20 are soldered to the connection points of the associated circuits on the printed circuit board 30.

FIG. 5 clearly shows the protruding hooks 31 of the pin holder 20 which interact with the closely spaced tubes 35 during the soldering process. This assembly of pin holder 20 and contact pin array 22 is selectively attached to a printed circuit board 30 (not shown in FIG. 5) using hooks 31 and tubes 35 only during the soldering process. The soldered bond, the pin holder 20, the contact pin array 22, and the printed circuit board 30 are bonded together in the groove 33 of the base plate 21.
The hook 31 and the base plate hook 34 are fixed to each other with bolts.

It will be understood that the multiple series is an embodiment of the present invention, and that it can be modified into multiple forms without departing from the purpose of the present invention.
